PENCIL SHARPENING -DEVIGE Filed Nov. l, 1928 Patented June `2, 1931 UNITED STATES GEORG KNIG, or BERLILLDA'HLEM, GERMANY PENCIL SHARPENING- DEVICE Application led November 1, 1928, Serial No. 316,459, and in Germany November`12,`1927.` A

The present invention relates to a device,I for shar ening pencils combined with a receptacle intended to catch the shavings or chips resulting from sharpening, the object being to provide an improved device of this y kind which is convenient and easy to handle, inexpensive to manufacture, and adapted to permit the Sharpener to be used at different working angles with relation to the receptacle or base part on which it is mounted.

According to the present invention this is achievedby mounting the Sharpener by a universal joint on a base part formed as a receptacle for catching the shavings and chips, said joint enabling the Sharpener to l perform swinging motions only butJ not al` lowing the same torotate about its own axis.

A further feature of the present invention is the provision of eyes formed in lugs in an opening of the receptacle by appropriate stamping and bending operations therein; these eyes forming bearings for a hinged frame in which the Sharpener itselfVV is pivoted.

The cost of manufacture may be reduced i by manufacturing said frame from a strip of sheet metal and pressing up the trunnions or pins of the universal joint therefrom, said pins being journaled in the eyes on the receptacle and in the Sharpener itself.

One example of an embodiment of the invention will now be described by way of eX- bore 6 and'acutter' V7.

on line 6-6 of Fig. l through the'A Fig. 7 sans@ elevacin ofthe Samej Referring now more particularly to the drawings, 1 is' a supporting base, which is cup-shaped and serves also Vasa receptacle for the shavings and chips resulting from sharpening. 2 is a sharpening device or member pivotally supported for lateral swinging movements yin Van open oblong rect-'angular frame 3, which, in turn, is pivotally mounted j Afor swinging Vmovementsin a vertical plane in eyes l provided influgs 5,vr formed ,on the receptacle. As shown in Fig. 2, thesharpi-V ening'device or member 2compri`ses aslotted y `metal body or shoe provided ,with atapered The receptacle 1 is formed at onejside. with any opening intersecting itsrim edge, and the lugs 5y are formed, byjpa-rts of the metal displaced to providesaid'opening.

The frame 3l is.` arranged in theopening between the lugsl 5, and the sharpening device or .member 2 is mounted in and' enclosed by nsaid frame and projects inwardly beyondthe said opening into the receptacle. ,j

. As shown particularly in Figs. 6 and 7, the frame 3, which is made from a strip of sheet j vmetal bent into form, ispro'vided with pressed vout ,truniiions or joint pins 8 and 9,

by means of which theframe is pivotedin the eyes ALlof the lugsv 5. lThe fra-me is also pro- A yided withpressed out y,trunnions or joint. pins H1() y andll engaging 1nl "correspondingk sockets-or openings inthe sharpenmgde'vice 1Q, whereby thelatterisvpivotally mounted in said frame. f'

A.s will be evident` fromthelforegoingde- 1`so scription`,the sharpening deviceis, by its pivetal connection with the` frame 3, and the pivotal connectionwof thelatter with the sup` .Y

porting base ory v'receptacle `l, universally jointed to said receptacle, yso' that said sharp` ening device is capable of performing swing .ing movements relatively tothe receptacle ,in

two directions or` planes atfright angles to each other. "By this means the sharpening deviceis adaptedto i beadjusted to operate Y portion, a frame pivoted on the base portion,

at different angles, both vertically and laterally With relation. to thev receptacle,v so that the sharpening operation'may be performed at various Working angles in an easy f and convenient `manner and under conditions Which would otherwise be awkward convenient. n l s Having4 thus described'my invention, 'l claimt:

l. A pencil Sharpener consisting of a-base and in- 'shavings and having'eyes aty the rim edge fthereof, a' frame hinged toy the eyes, and a sharpeningdevice hinged tothe frame. y 4. AV pencil Sharpener consisting of a Vbase Vportion formed as a receptacle for pencil shavings, a plate metal frame having two sets of pressed-outgolnt pins, one set engagl0. A pencil Sharpener7 comprising a base member adapted to receive pencil shavings,Y

and a sharpening device sWingingly attached l to said hase member and with its dischargev portion extending thereover. Y

ll. A pencil Sharpener, comprising a base inem-ber adapted toreceive pencil vshavings, and a nonrotatablefsharpening.device swingingly attached to said base member and With its discharge portion extending thereover.

In testimony whereof I aix my'signature.
